Can now really see when backing up.

Significant improvement over original bulbs. I replaced almost all of the bulbs in my 2010 Mazdaspeed3 with Alla LED bulbs.

Pros
  • Stylish and modern design
Cons
  • Doubtful

Good lamp upgrade

I've always been interested in "upgrading" my wife's 2011 reverse lights. The car is in excellent condition but without a reversing camera. She starts work early in the morning and the light makes it easier for her to reverse. She had her doubts but changed her mind after I installed it (which by the way was easy, no adapters, with factory bulbs and everything was fine). A small but worthwhile investment in safety and comfort!

Pros
  • Excellent overall performance
Cons
  • Hard to say

2nd best of 3 brands I've tested

I bought these, plus JDM ASTAR 1200 lumens 144-EX 7440, plus OXILAM backup reversing light 7440. They were all pretty good but they 2nd place were best for brightness, whiteness and a nice even pattern of light petals. Best was JDM ASTAR followed by OXILAM in third place. Like I said, they were all pretty good, but these were second best. Used in the 2016 Mazda 5 as well as the 1997 Honda Civic. One thing you should be aware of though: NONE of these three will fit in the reverse lamp sockets on

Pros
  • Easy to use
Cons
  • I vaguely remember
